Renners, u end with e. vertically disposed series of citizen of the United States, residing at forutions 7 and e. pin 8 is supported by' t o Pope, in the county of Perry und State of snidi'ranie 5. A double treen;x sli-deel on rlennessee, have 'invented n new and usetul mount-ed upon. the pin 8 and is 'provided Soildlulverizing Attaclnneut for Plovvs, of with rearwardly disposed lugs 10 which nre which the following is a specification. adapted to receive between them the reur This invention relates to u soil pulveriz'ing portion of the trame 5 and through perfo-- attachment for plows, end it consists in the rations in which muy be passed a pin il., o5

The object of the invention is to provide ivllbe Seen that ineens 's provided for adit Soil pulverizing attachment es indicated Fisting' and supporting the double tree 9 which includes a wheel mounted treme to vertically upon pin 8, A. link l2 is ndjust- Zo 5 which may be attached a plow. A secondary ably secured upon the double tree gend confrnme is adjustably attached to the first Seid nects n clevis 13 which in turn is connected frame and is held in desired relation to the with lll@ forward end 0f e plow 'boom li. same under spring tension which muy be inliv this arrangement it will be that creased or diminished desired. .e rotor-s Ineens is provided for supporting the turf .75 2o mounted in the said secondary frame and is Word @mi 0f the plow beam il: in. il relatively n provided with chopping blades of peculiar high or low position and also for edjusting configuration und arrangement and so the plow beam to one side or the other of mounted that each alternate blade moves the tongue 4. p radially as the rotor .turns upon its axis. the 1li secondary trame edjustubly uttacl :d so' object being that by providing the said rato the primary f runie lA and the said second dial movement on the part of the uhm-nate ary iframe includes resilient side strips .l5 blades the said blades will keep themselves which ure udjuslubly.secured at their upper 'free from the. aecumulution of soil or trash. forward ends by ineens oif boils 13C: which The arms i spokes of the. adjacent blades pass through perforations provided ill illiri-o 3o of the rotor are in staggered relation. along Said strips 1.5 und peri'orations i7 provided the axis of the .rotor which relation 'is also in the fiume l.. The lower rear ends ofthe for the purpose oli' reducing the possibility side strips .l5 are connected with the forof the accumulation of trash or stalks bewurd ends` of rigid side bars 18 und the Suid tween the blades ol the rotor. Soil pulver; bars 1S are designed to normally occupy oo izing devices are carried nl. the rear end por horizontal positions or appioxinmtely so. tion of the Secondary frame and. .operate A standard 19 is mounted upon the primary upon the surface ot' the soil in the nmnocr tramo l and is provided with a toothed seg hereinafter explained, nicht 20. level' 2l iS fulci'lllned t0 the In the accompanying drawings, Figure l upper portion oi' the standard 19 and is 95 40 isc top plnn'view of the. soil-pulverizing dcprovided with n spring actuated pr-Wi 22 Vice connected with u plow.

Fig. 4 is a per- A. shaft 25 passes transversely through the 10o spective View of a supporting bar Jforming slot 2i in segment 23 and is provided et its a component part of said rotor. Fig. 5 is n ends with bearings 2G to which are attached vertical sectional view` of an end portion of the forward ends of curved springs 27. The

iii-amel which is mounted upon an axle 2 nent parts of the secondary treme of the which in turn is supported byground wheels soil pulverizer attachment. By swinging 3, a tongue al is connectedl at its rear portion the lever 2l it will be seen that the tensiono't" with the intermediate port-ion'of the frame the spring 27 may -be increased or diminl and is provided upon its under side with a ished and thus the resilient force with which 110 draft frame 5 which is slidably mounted in `the secondary frame of the attachment is l guides or supports 6 in, any appropriate held toward the ground may be adjusted.

@t ier cross bars 29 (similar to the bar QS) torni eomponent parte of the secondary frame of the attachment and the cross bers 28 29 carry soil pulverising blades 3G which et their: rear portions are ivna'erably disposed sente angle to the line of draft of the glow and its attachment,

Spindles are attached to 'the side bars i8 and project inwardly therefrom. Disks are eceentrically and xedly mounted upon the spindles' 3l adjacent the inner sides of 'the bars 18 and rings 33 are fixed to the inner sides of bars 18 and are concentxrieally arranged with relationto, the disk 32. The inner edges of the rings 83 are spaced from the peripheries of the disks 32. Disks are concentrieally mounted upon the inner portions or' the spindles 3l and are jonrnaled for rotation upon the said spindle. The disks are provided at diametric-ally opposite sides with elongated slots which are radially disposed. Cross bars 3o are provided at their ends with projeetinrf;- pins 37 and 38, the pins 38 being longer than the pins 37. The outer end portions of the pins 37 lie in the elongated slots of the disks 3e but do not traverse the pl ne., of the inner sides of the disks 82. The 38 profeet. through the elongated slots 35 inthe disks di and the outer end portions the pins 38 lie in spaces between the disks 32 and rings E33. Spokes 39 are mounted upon the bars 36 and at their outer ends port chopping biases et). Bars el ,o the disks dei et their ends and loont. l at diarnetrioslly oploof the s d disks Spokes l2 orted by the bars il and the said spokes at their outer ends support chopping blades disks ond ba. s .36 and el together with their attachments constitute the rotor above referred to 'and it will be seen that as the rotor turns upon the axis oi2 the spindles 3l that the projecting pin 38 in Contact Wit-h the per'pliery of the disk 32 will canse the spokes 39 and blades move radially with relation to the axis of the rotor as they rnove about the same. Thus as the said blades encounter the Asoil and move away from the same their radial movementl with relation to the axis of' the rotor will prevent the'material from Wedging between the spokes 39 and blades 40 and the spokes et? and blades 43. While the spokes e2 and' blades 4-3 rotatel about the axis o the rotor they are confined against radial movement with relation to the said axis. The spokes 4:2 are in the vicinity of the ends of the bars 41 While the lspokes 39 are removed froml the ends of the bars 36 and hence the spokes arevin staggered relation about the axis ot the rotor and such staggered relation further removes the possi-f4 bility of the said spokes accumulating? trash or other objectionable material.

Having described the invention What claim as new and desire to secure by Letters Patent is l. A soil-pulverizer eomprisingr a, frame, a rotor journaled in the trarne, blades carried by the rotor, some of said blades being mounted to move radially `vith relation to the axis of the rotor as they move about the same and otlieror" the blades beingV fixed with relation to the axis of the rotor.

2. il soil-pnlverizer comprising a' trame, a rotor journaled in the 'frame and consisting of disks, blades fixed at their ends to the disks, other blades carried by the disks and adapted to move with relation to the axis of 80 the rotor7 the last said blades having projecting pins and disks eccentrically mounted upon the frame with relation to the axis of the rotor and engaged bysaid pins.

In. testimony that l Claim the foregoing as 85 my own, l have hereto afixed my signature in the presence vof two` Witnesses.
